Eaton M90 or Eaton M112?

See the above picture of the side mounted blower?
Basically that, but the injectors angled to aim at the back of the intake valve. The injectors and fuel rail will be mounted to the intake manifold, much like any modern vehicle
Are you making your own manifold? It looks like the side mount one was custom made.
I really like that side mount design. As for which blower, I would personally go with the 112 just because its bigger. Adds a greater "Oh sh*t" factor when you open the hood if you have a big blower under there :D
